SELF-WAITING TABLE.

SPECIFICATION forming part of Letters Patent No. 723,269, dated March24, 1903.

Application filed February 7, 1902.

To all whom it may concern:

Be it known that I, MARTIN V. 'HAMMAOK, a citizen of the UnitedStates,residin g at'lhalia, in the county of Princess Anne and State ofVirginia, have invented certain new and useful Improvements inSelf-Waiting Tables, of which the following is a specification.

My said invention consists in certain improvements in the details ofconstruction of self-waitingtables whereby a table of such character isprovided which will be very convenient in use and easy to operate andwill not materially shade the main table below, and thus beobjectionable, all as will be hereinafter more fully described andclaimed.

Referringto the accompanying drawings, which are made a part hereof, andon which similar reference characters indicate similar parts, Figure 1is a perspective view of a table embodying my said invention; Fig. 2, acentral section through the upper portion thereof, and Fig. 3 a top planshowing a modified form of the serving-table.

The main table Ais of any desired form 2 5 round, square, or octagon-asshown being preferably of equal dimensions on the several sides. It ismounted on a suitable frame and legs, such as shown, or of any approvedform. It is provided with a'centr'al perforation, and 0 on the undersidea plate 1) is secured to furnish the required 'stiifness and supportand afiord a socket in which is mounted a vertical rod 1, the head beingcountersunk into said plate to prevent it from turning. Said tion insaid table to the height desired and has a screw-threadedtop. On the topof said table is a sleeve or hollow standard 2, mounted around said rod,in the top of which is formed 40 half a ball-race for the balls 3, onwhich the serving-table B is mounted. Said servingtahle B is formed witha solid center and several radial arms B, preferably in the form of astar, the arms or points being adapted to serve as rests for the disheswhich are to contain the articles toube served. The spaces between thearms orpoints may be filled with plates of glass 19*, held in place by aband b as shown in Fig. 4, to. make a Wider surface Serial No. 93,013.(No model.)

the table below. Said table is provided with a metal ring 6 on its lowerside, having an aunular groove in its face, which serves as a bearingfor the balls 4 in the ball-race of standard 2. It is also provided witha similar ring I) on its top surface, having an annular groove in itsface,which constitutes part of a ball-race for the balls 4:. Said tableis centrally perforated and mounted on the rod 1 and is secured thereonby a not 5, mounted on the screw-threaded upper end of said rod, andformed with an annular groove in its lower face, which constitutes theother half of the ball-race for the balls 4. By this means said table issupported and adapted to turn on ball-bearings both above and below,which renders its operation very easy and its support very rigid. On thetop of nut 5 is formed or mounted a small shelf 6,which may be used forthe support of a lamp, a vase of flowers, or

any ornament or other article desired. By this arrangement theserving-table will not materially interfere with the use of the tablebelow by making the space beneath it dark, and a very convenient tablefor the purpose is provided.

In providing the table with a cloth it will -be necessary to make acentral aperture in said cloth of the size of the rod 1, when it may beput in place by first removing the serving-table B and other parts bytaking ofi the nut 5, when the cloth can be put in place and said partsreplaced, as will be readily understood.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a self-waiting table, the combination, of the main table-top, acentral pivot-and-tie rod extending up through said table-top, a 0

hollow supporting standard having a large base and top and mountedaround said central rod with its base resting upon said table-top,

the serving-table mounted to rest upon the top'of said hollow standardand supported thereon and adapted to rotate around said central rod, anda nut on the top of said rod for securing the several parts together,said several parts being separable by removing said nut, whereby theymay be removed for 10s the purpose of placing a table-cover upon orremoving it from the main table-top, substantially as set forth.

2. In a self-waiting table, the combination, of the main table-top, thecentral rod extending up through said table-top, a hollowsupporting-standard with wide base and top surrounding-said central rodand resting upon said table-top, the serving-table mounted to rest uponthe top of said standard and revolve around said central rod, ball-racesin the top of said standard and adjacent face of said serving-table,balls mounted in said ball-races, the-nut on'the top of said rod forsecuring the parts together, ball-races in the lower face of said nutand adjacent face of said serving-table, and balls mounted in saidball-races, the several parts being separable by removing said nut,substantially as set forth. I

3. In aself-waiting table, the combination, of the main table-top, acentral rod or post extending up through said table-top, a 1101- lowstandard mounted around said rod and to rest upon said top,the revolvingstar-shaped serving table mounted on the top of said standard above saidmain table top, said serving-table being formed with a central surfaceof sufficient size to support dishes to be placed thereon and havingradial tapered arms projecting from said central portion, the

spaces between said arms being filled with.
